SNAP-FASTENER.

Specification of 'Letters Patent.

Patented J an.

Application filed July 5, 1917. serial n0. 178,7o1.

To all 'whom/'it may concern:

Be it known that I of. Rochester, in the county of Monroe and State of New York, have invented certain new and useful- Improvements in -Snap- Fasteners; and ho hereby declare the following to tion of the same, reference being had to the .this specification, and

-mem er;

accompanying drawings, forming-a 'part of to the reference-numerals marked thereon.

My present invention relates to fastening devices of an attachable-nature such as are used upon automobile curtains and in other instances where it isdesired to temporarily attach two fabrics or fiexible sheets together and 'the invention has for its object to provide a simple, strong and durable snap fastener of this can be engagedy and disengaged with great convenience and when in coperation with each other are prepared to resist considerable strain. To these and other ends the invention resides and combinations of parts, all as will be hereinafter more fullytlescribed, the novel features being pointed out in the claims at the end ofthe specification.

In the drawings:.

Figure 1 is a plan view of the socket mem-l ber of a fastening device constructed in accordance with and illustrating one embodiment Aof my invention;

Fig. 2 is a similar view of the button or other attaching part;

Fig. 3 is a plan view .of the spring plate;

Fie. 1 is a bottom plan view of the socket Fig. 5 is a section on the line 5-5 of Fig. 1 showing the two parts of the fastener encaged;

Fig. 6 is a section on the line 6-6 of Fig. 5, and v Fig.l 7 is a section through the button, cnlar ed and partly in elevation.

imilar reference numerals throughout the several views indicate the-same parts.

Referring more particularly to the dra'wings, 1 indicates a fragment of a curtain, in the present instance, and 2 a fragment of a support to which it is to be temporarily fastened. One of the fastening elements 3 is sc` cured to the support 2 and consists of a turret-shapedhollow'socket member the body of which is offset from the support and is WILLIAM F. FOLMER,

be a full, clear, and exact descripcharacter the parts of which' in. certain improvements Y and displaces head 10 to clcarthe recess flanges Ao under side the socket is provided with a. circular recess 6to which accessmay be had in a lateral direction through 11n-opening 7 in the side of the turret in connection with a slot 8 in the top thereof. Beneath the socket and the attaching flanges 5 thereof and secured to, the support 2 by the same fasteners 4, is a' spring plate 8 shown in Fig. 3. Centrally of this plate a spring tongue 9 is struck from the material thereof to present a rounded surface in the direction off beneath the slot 8, as

the recess 6' directly shown in Fig. 6. f

The other attaching element that is car ried on the curtain lfconsists o f a button havinga circular head l0 and a shank or stem .11'. In the present instance, t-he button is secured to the curtain by means of a rivet 12 extending through the head 10 of the stem 11 and expanded or upset at 13. A washer at the base ofv -the turret. Oni-ts 14 is preferably interposed between the stem.

lland a shoulder 15 on -the rivet.

To attach the curtain 1 to the support 2 the button is passed laterally into theturret-shaped socket member 3, the head 10 entering through ,the opening 7 and the stem 11 through the slot 8. The head 10 engages posite the recess 6 when the spring forces the spring tongue 9 until op the head outwardly into the said recess and locks'it there against passage back throu h the opening 7. Vhile the opening 7 inclu es part of the lateral wall of the recess 6, lthe circular nature of these walls provides shoulders 16 (Fig. 4) that retain the head 10 from movement in the direction of the opening becausethe head 'closely fits the recess. It v'ill be observed that the -head has an extendail beari g against the bottom of the recess so that i spring 9.

To release the button and separate the elements and the fastener a reverse rnotiouis imparted toit, namely, it is pressed straight in to displace the spring 9 and allow the shoulders 16 thereof and it is then drawn out laterally throughv the opening 7 and slot 8.

I claim as my invention:

1. In a snap fastener, the combination with an offset socket member havin 'a lateral opening and a recess in its un er side, ofa button comprising a stem and a head adapted to be inserted 1n the opening of the does not rock or tiltek and" it is' held in this bea-ring at all times by the 6' and the :locking fie:

socket member into elinement with the recess nd e s rin dbeneath the-socket member ede tolle ispled by the entrance of the utto'n and to thereafter thrust the let-l i ter into the recess. 4,1;2. In'V -sna f tener, the combination with a turret-s aped socket member having a lateral opening and a circular rece in its under islde' forming :in annular seat, "of a button'comprsing e stern-ande4 circuler -r head adapted vto be inserted-in the opening othesocket into a-lnementwth the recess, and 'a spring' beneath the socket`me1nber` adapted to be di'pplaeed, by the entranceof the button :amdto thereafter .thrustthe latter into the ann alrrecess;

`3. Inia. sna fstener,- the combination with e turret-s a'ped socketniem'ber having a lateral'openingand a-circu'ler recess in its underslde formlng an annulernsmtfpf ai:

button-'comprising a stem and a Vcirculer headl adapted to be inserted in the opening ofV the socket'nto alnement with the recess,

attaching anes on the socket member at the base of .t e turret portion thereof, a spring plate beneath the agee and. turret portion adapted to be secu'rll to a support therewith and a spring tongue on the plete beneath theturret portion adapted to Vbe displaced'by .the entrance of the button und to thereafter thrust the'letter into' the annular-recess,
